Neco Model Questions Vol1 2023 Physics Question 41
Practice objective / multiple choice question 41 from the 2023 Neco Model Questions Vol1 Physics examination.
A copper rod of mass 2.0\,kg (specific heat capacity 0.385\,kJ\,kg\^{-1}\,K\^{-1}) is initially at 150\,°C. It is placed in perfect thermal contact with an aluminum rod of mass 1.5\,kg (specific heat capacity 0.900\,kJ\,kg\^{-1}\,K\^{-1}) that is initially at 30\,°C. Assuming no heat is lost to the surroundings, what is the final equilibrium temperature of the combined system in \(^\circ\)C? Give your answer to one decimal place.
